Ipayipi lokufafaza umlilo kanye nokufakwa okuhlobene ngokuvamile kwenziwa nge-carbon steel noma i-ductile iron material futhi isetshenziselwa ukuthwala amanzi noma olunye uketshezi ukuxhuma izinto zokucima umlilo.Ibizwa nangokuthi ipayipi lokuvikela umlilo kanye nezixhumi.Ngokwemithetho namazinga ahambisanayo, ipayipi lomlilo lidinga ukupenda ngokubomvu, (noma nge-epoxy anti corrosion coating ebomvu), iphuzu liwukuba ngokuhlukana nolunye uhlelo lwamapayipi.Njengoba ipayipi lokufafaza umlilo livamise ukufakwa endaweni emile, lidinga izinga eliphezulu futhi likhawulele ukulawulwa kwekhwalithi.
Ngamafuphi nje, ipayipi lokufafaza umlilo nezinto ezifakwayo kufanele zibe nokumelana okuhle nengcindezi, ukumelana nokugqwala kanye nokumelana nezinga lokushisa eliphezulu.
Imingcele yezobuchwepheshe yamapayipi omlilo
I-Coatings: Isistimu yokuhlanganisa i-epoxy esindayo elungisekayo
Umbala wendawo evamile: Obomvu
Ubukhulu be-coating: 250 um kuya ku-550 um.
Ibanga losayizi: DN15 kuya ku-DN1200
Izinga lokushisa lokusebenza: -30 ℃ ukuya ku-80 ℃ (Phezulu 760)
Ingcindezi yokusebenza evamile: 0.1 Mpa ukuya ku-0.25 Mpa
Izinhlobo zokuxhuma: Intambo, i-Grooved, i-Flanged
Izicelo: Amanzi, igesi, ukudluliswa kwebhamuza lokucisha umlilo nokunikezwa
Izinhlobo zokuxhuma zamapayipi omlilo e-DN ahlukene
Ukuxhumeka okunentambo nokuhlanganisayo: Ngezansi kwe-DN100
Uxhumano lwe-grooved kanye ne-clamp: DN50 kuya ku-DN300
Ukuxhuma kwe-Flange: Ngaphezulu kwe-DN50
Okushiselwe: Ngaphezulu kwe-DN100
Uma kwenzeka ipayipi lomlilo lifakwe endaweni engaphansi, ukushisela yiyona ndlela eqine kakhulu, engasebenzisa ukushisela insimbi ephindwe kabili futhi ingalimazi, ngale ndlela ukuvimbela izinkinga ezibangelwa ukulimala kwe-epoxy coating noma ukuqhekeka kwepayipi ekuncipheni kokuma komhlaba.
Izici ze-epoxy coated fire pipe
Ipayipi lomlilo eline-epoxy enamathela ngaphakathi nangaphandle, lisebenzisa impushana ye-epoxy eguquliwe, enokumelana okuhle nokugqwala kwamakhemikhali.Ngale ndlela ukuxazulula izinkinga ezinjengokugqwala kwendawo, ukugqwala, ukukala kwangaphakathi nokunye, nokuvimbela ukuthi ungavimbeli, ngokugqamile ukwandisa ukuqina kwepayipi lokufafaza umlilo.
Ngakolunye uhlangothi, izinto ezifakazela amalangabi zengeziwe ezimbotsheni, ukwenza ukumelana nokushisa kwepayipi lokufafaza umlilo kube ngcono kunezinye izinhlobo zamapayipi.Ngakho ngisho nokushisa okusebenzayo kukhula ngokushesha ngeke kuthinte ukusebenza kwepayipi lomlilo.
Ngakho-ke, ipayipi yokufafaza umlilo ukuthi nge epoxy enamathela yangaphakathi nangaphandle, lokho kungcono kakhulu kunepayipi lashukumisa phezu ukuqina nokusebenza.
Ukunquma ukuxhumana okulungile kwamapayipi okufafaza umlilo
Njengoba sazi ukuthi kunezinhlobo ezine zokuxhuma ukuxhuma ipayipi lomlilo noma okokufakwayo.Okungukuthi: uxhumano oluyi-grooved, uxhumano lwe-flange, uxhumano lwe-butt weld kanye nokuxhumeka kwentambo.
Kungani kufanele usebenzise ukufakwa kwepayipi lokufafaza umlilo
Ukufakwa kwepayipi lokuxhuma kuphela okuhambisana nezindinganiso ezifanele kufanele kusetshenziswe uma kwenzeka noma yikuphi ukuguqulwa kobubanzi bepayipi ezinhlelweni zamapayipi omlilo.
